fun leveling systems.
level 1
very easy mobs: can be killed with 1 player, can be killed while hp more than 10% (example: rabbit,deer)
easy mobs: can be killed with 1 player, can be killed while hp more than 50% (low level bandits)
medium mobs: can be killed with player, can be killed while hp more than 80% (medium level orcs)
hard mobs: can be killed with 1 player, can be killed while hp more is full 100% (high level undead)
legendary mobs : group events need at least 10 players (level 1) to defeat it.
mvp mobs: need 20 level 100 players to defeat it. (so max level can come back to low level area to defeat mvp)

The most fun leveling system i ever see is log in , give few click to collect the exp and after that do something else that not PVE combat .
And get level up after few h of auto collect exp , or take few day of login at higher level .
let leveling being reward of log in and do something else in game that not leveling hahaha
All you've described is a system whereby your success or failure rate is arbitrarily decided by your current health. Where is the fun in that? To me, that is a massive step backwards.
Fun is determined by what you actually do, i.e. the gameplay. You've not even attempted to discuss the gameplay.
I'm all for sharing new ideas on these forums, but you should at least have a fully formed idea before you start, followed by a coherent explanation of that idea in your post.
Admittedly, that had nothing to do with "leveling" as such, though, apparently, this is some kind of reward system, on line with silly achievements.
